Greenhouse Gases Carbon Dioxide
285 wordsLike the glass in a greenhouse, certain gases that occur naturally in the atmosphere tend to trap the suns heat. This natural " greenhouse effect" helps keep the Earths average temperature at a comfortable 59? Fahrenheit. Without these greenhouse gases, the Earth would be about 0? F, like a deep- frozen snowball. But human activities are causing some greenhouse gases, such as carbon dioxide, to build up in the atmosphere. Whenever we burn fossil fuels (gasoline, oil, coal or natural ga...
